The German Instrument Pool for Amphibian Seismology (DEPAS) provides the infrastructure for onshore, marine and amphibian seismological experiments. It consists currently of approx. 80 ocean-bottom seismometers (OBS) and 95 onshore seismic stations. Broadband sensors and custom-built data loggers enable a broad range of short- and long-term deployments to study architecture and dynamics of the Earth’s interior. The OBS are operated by the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI); the onshore stations are managed by the Helmholtz Centre Portsdam GFZ German Research Centre for Geosciences. The DEPAS instruments are available upon request for researchers affiliated to German universities or German research institutes within national or international projects. Applications for stations are evaluated by an external steering committee. Data will be stored in national archives and made available to the public after a waiting period.
